Do you fertilize peonies in the fall?

Answered by Douglas Hiatt

It is recommended to fertilize peonies in the fall after they have been cut back. This is an important step in maintaining the health and vigor of the plants. Fertilizing in the fall provides essential nutrients that will support root development and overall plant growth.

When fertilizing peonies in the fall, it is best to use a balanced fertilizer with equal amounts of nitrogen (N), phosphorus (P), and potassium (K). A 1-1-1 fertilizer, such as a 10-10-10 or 13-13-13, is a good choice. These numbers represent the percentage of each nutrient in the fertilizer.

To determine the amount of fertilizer needed per plant, a general guideline is to apply 1.5 to 2 ounces (or 3 to 4 tablespoons) of the 1-1-1 fertilizer. This can be evenly spread around the base of the plant, avoiding direct contact with the stems or foliage. It is important to follow the manufacturer’s instructions for the specific fertilizer being used, as the application rates may vary.

When applying the fertilizer, it is helpful to lightly scratch it into the soil surface or gently water it in to ensure proper absorption. This will allow the nutrients to reach the root zone where they are needed most.

Fertilizing in the fall is beneficial for peonies as it helps replenish nutrients that may have been depleted during the growing season. It also provides a boost for root development, which is essential for the plant’s overall health and ability to withstand winter conditions.

In addition to fall fertilization, it is also recommended to fertilize peonies in the spring, shortly before new growth appears. This helps provide nutrients for the upcoming growing season and supports the development of strong, healthy blooms.

In my personal experience, I have found that fertilizing peonies in the fall has had a positive impact on the overall health and vigor of the plants. It has helped them to establish strong root systems and produce abundant blooms in the following spring and summer. By following the recommended guidelines for fertilization and using a balanced fertilizer, I have seen noticeable improvements in the growth and flowering of my peonies.

To summarize, fertilizing peonies in the fall is an important step in their care. Using a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium will provide the necessary nutrients for root development and overall plant health. Applying 1.5 to 2 ounces of fertilizer per plant and evenly spreading it around the base of the plant will ensure proper absorption. By fertilizing in both the fall and spring, peonies can thrive and produce beautiful blooms year after year.
